Central Asian states and Pakistan, Iran, Turkey and Azerbaijan have agreed to set up a fund to help rebuild Afghanistan. The decision came at the end of a meeting of the Economic Cooperation Organisation (ECO) in the Turkish city of Istanbul. The meeting was held to ensure the pledges of billions of dollars in aid to Afghanistan are kept - Kabul has received much less aid this year than it had hoped for. This was the first ECO summit to take place since the Taleban were ousted from Kabul. On Monday, Afghan President of Hamid Karzai called on the member states to make a firm contribution towards the reconstruction of his country. Mr Karzai also used the first ECO summit since he was installed in office to urge rapid progress on a subject close to his heart - the construction of a pipeline through Afghanistan that will transport gas between Turkmenistan and Pakistan. The pipeline, which would bring badly needed cash into the Afghan economy, was originally conceived five years ago but has been on hold during the conflict to oust the Taleban. This forum's hosts, Turkey, are currently playing a key role in Kabul, having taken command of the Isaf security force. The emphasis being placed on Afghanistan has pushed other important regional issues down the agenda. These include what is seen as the main purpose of the expanded ECO - the integration of the weaker central Asian economies with those of its main economic powers, Turkey Iran and Pakistan - ECO's three founder members in 1985. The summit is also an opportunity for the big three to reflect on ways to draw back from their past regional rivalries and to work in concert for the development of the region as a whole. (BBC)
